Branched Structure

Ultraviolet (UV) curable waterborne polyurethane dispersions with comb branched structure were synthesized by prepolymer process. C=C bonds were incorporated into the branched chains of the polyurethane using chain extender, hence, the content of C=C bonds can be adjusted by the chain extender consumption. The chemical structure was identified by Fourier transform infrared spectroscopy (FTIR) and1H NMR. Effects of the chain extender content on the microstructure, rheological behavior, thermal property, mechanical and other properties of the UV cured films were researched.

Adhesive Materials

A series of waterborne polyurethane (WBPU)/modified lignin amine (MLA) adhesives was prepared using modified lignin amine (MLA) as a chain extender by a prepolymer mixing process. A successful Mannich reaction was achieved during the synthesis of MLA by reacting lignin with bis(3-aminopropyl)amine. Higher tensile strength, Young’s modulus and thermal stability were recorded for WBPU/MLA adhesives with higher MLA contents. The WBPU/MLA adhesive materials were used to coat PVC substrates. The adhesive strength increased with increasing MLA content. More importantly, the MLA also enhanced the WBPU/MLA coating in terms of adhesive strength at moderately high temperatures as well as under natural weather exposed conditions. The adhesive strength was essentially unaffected with 6.48 mole% MLA in the WBPU/MLA coating after exposure to natural weather conditions for 180 days.
